Ways of Selecting a Flow Meter An instrument that is used to measure the flow rate of liquids and gases is a flow meter. When buying a flow meter one should take into consideration the familiarity of the working personnel with the device and their experience with calibration. Also one should consider the maintenance factors such as availability of spare parts and the probability of failure. The cost of installation one should also take into consideration. Because a device is less expensive one should not buy it since this can be the most costly installation. One can consult an installation engineer when buying the flow meters just in case there are any flow measurement challenges. Evaluating the nature of the process fluid and flow characteristics are the basics to selecting the best flow meters. The piping and the area the flow meter is to be located one should also consider. The characteristics of the fluid to be considered are the pressure, temperature, viscosity, density and many others. Of how they should interact these properties should have an indication for the flow meter to operate properly. A detailed composition of the fluid should also be there. That one should indicate whether the fluid has solids and whether they are soft or abrasive or whether they have small or big particles this is to say. One should know the required meter range so that they can select the best meter and this is done by identifying the minimum and maximum flows that will have to be measured. Over its full range the flow meter’s performance may not be accepted unless one knows the measurement accuracy. The flow meters without moving parts one should choose over the ones with them when purchasing flow meters. Usually the flow meters with moving parts are a cause of problems and failure since the moving parts are prone to wear and tear. Clearance spaces for the moving parts that sometimes cause slippage into the flow being measured they also require. Included in the different types of flow meters which are there are; rotameters, piston flow meters, paddlewheel, turbine flow meters, ultrasonic flow meters and magnetic flow meters. Available for in-line and insertion type the magnetic flow meters are. Ideal they are for any waste liquids that are conductive. Usually the displays are integral and an analog output can be used or remote monitoring. For dirty water or waste water the ultrasonic flow meters are also used. The principle of operation employs the frequency shift of an ultrasonic signal when it is reflected by discontinuities in the liquid flow. On the other hand the rotameter is the most used for liquids and gases.Lessons Learned About Meters
